특허분석을 이용한 합성수지류 폐기물의 관리 기술동향과 공백기술 조사

The objective of this article is to investigate technological trends and forecast vacant technology in the area of syntheticresins waste processing (SRWP) by the patent analysis. We extracted and analyzed 4,748 patents related to SRWP, grantedin Korea, Japan, China, the U.S.A., Europe, and PCT between 1997 and 2016. The results indicate that 1) the numberof patents deposited on SRWP grows every year; 2) the main depositor countries are China, Japan, Korea and the U.S.A.;3) China is in the developing phase of the technology market and showing the most drastic growth; 4) there is a prominenceof deposited patents for plastic waste technologies; 5) the patents on SRWP are concentrated in the area of recycling forthe recovery of material by physical process. The result of OS-matrix analysis for forecasting vacant technology in SRWPsuggests that rather than ‘incineration and landfill technology’, which has emerged as a vacant technology in the globalmarket, it is necessary to focus more on the ‘recycling and reuse technology’ that are urgently needed in Korea as follows;1) recycling technology for polypropylene waste; 2) reuse technology for polystyrene waste; 3) more aggressive effortsto technology development for the disposal of polyvinyl chloride waste.
